Totals still down.

On an almost identical night a year ago my total was 40% greater than it was last night although the species number was very little different. On looking back totals of Dark Arches, Heart and Dart, Uncertain/Rustic and some of the other commoner moths are well down. Is this general with others?
As recompense,however, I was rewarded with my first Old Lady.

There are many factors at bay determining moth catch numbers. It's not just temperature, humidity and wind, but this past week there's been a bright moon. You also have to factor in the number of days since the last significant rainfall, as this will wash out a lot of moths and numbers have to build again afterwards.
